I know responding to a reddit post that's over 24 hours old is basically a waste of time but I can give you some recommendations beyond what Amazon thinks is cyberpunk. And I totally agree, the "cyberpunk" genre in Amazon is all lit-rpg and harem junk. I've been stuck reading the pulp stuff like Behind Blue Eyes, Code Flicker, Entropy Angels, and Into Neon. They're fine I guess.

As for actual recommendations, The Nexus Trilogy by Ramez Naam is really interesting. A guy creates a drug that can install programs into your brain and gets chased by various organizations. At one point the guy takes refuge in a Buddhist monastery and they discuss how his invention affects consciousness and human connectivity.

Another near-future light-cyberpunk I enjoyed was The Analog Trilogy by Eliot Peper. It's about how "the feed" can be used to manipulate a person's opinions and thought processes. The author intentionally never describes what "the feed" looks like because in this day and age we all have our own version of the "the feed". It's actually a very optimistic series and compared to the typical pulp crap I end up reading, this author's writing style almost feels like actual literature.

I guess I'll throw in one "pulp" series I found on Amazon that was pretty good. The Neon Horizon series is about a cyberpunk city where most people are monitored and tracked while living their corpo lives. But there's one district called The Blind Spot which offers full anonymity. There is no tracking whatsoever and people even wear face-concealing masks so no identities are ever revealed. This series is more full-on cyberpunk with high-tech low-lives struggling against the corpo lifestyle but it's rare to find a series that's actually about data privacy and anonymity.

Oh, I'll throw in one more book. Xenoform by Mike Berry was pretty surprising. Typical cyberpunk world... until Lovecraftian monsters start appearing. You don't typically see cyberpunk mixed with cosmic horror.

Check out The Peripheral by William Gibson for his updated view on cyberpunk. It's still more "near future" than contemporary but it takes the current world into account, rather than sticking with the 80s aesthetic. It imagines a rural community where 3d printing and VR are commonplace. Like, with a 3d printing shop at a strip mall.

The Nexus trilogy takes place in the contemporary world where someone invents a nano-drug that installs a computer in your brain. This series very much takes place in the real world, where the nano-drug is the only real change.

The Analog trilogy is another "near future" but I don't remember any massive improvements on technology. It's all about how "the feed" can manipulate someone's opinion. The feed is never fully described since everyone today already has their own "feed" they get their information from. This series is very much about social engineering, political corruption, and corporate lobbying. And each book is less than 300 pages.

Also, as the other commenters recommended, Daemon by Daniel Suarez was specifically written with current technology in mind. None of the technology in the story is made up. And Little Brother is a young-adult novel about a high schooler who tries to get around government surveillance. This novel tries to teach high schoolers about things like linux and encryption.

Then there's the WWW trilogy by Robert J Sawyer. It's about an AI becoming self-aware in 2009 (when the book was written). This series is almost painfully contemporary in that it's already out-dated. The author included things like livejournal and The Daily Show with Jon Stewart, which were relevant at the time.
